Last Control
Sign in · Operator entrance
Sixty seconds of arithmetic. The streak multiplier pays for nerve. A miss resets it.
Mental math practice, run the way the fabricators run it: against the clock. The problems start small and climb — two-digit sums, times tables, three-term chains, division. Three in a row doubles your points, six triples them, nine quadruples them. One miss and the multiplier is gone. Free, in the browser, no sign-up.
No download. No account. Sixty seconds exactly. The clock has never once been argued with.
Keys 1–4 answer the four options in reading order. The clock does not pause for either input.
The full audit runs in the game. Free. Anonymous until you claim a seat.
Frequently filed questions
Is this mental math game free?
Yes. Free, browser-playable, no sign-up, no download. Sixty seconds, scored on the spot, and the score stays on this page.
How does the streak multiplier work?
Every correct answer extends the streak. At three in a row the multiplier steps to ×2, at six to ×3, at nine to ×4 — and one miss resets it to ×1. The points the streak already earned are kept; the multiplier is not.
Does the arithmetic get harder?
Yes. The sprint opens with single-digit sums, climbs through two-digit addition and subtraction and the times tables, and ends in two-digit multiplication, three-term chains, and division. The clock ends the sprint at sixty seconds regardless of where you are.
Is this a real math or cognitive assessment?
No. It is a game. The rating is a game score for entertainment — it does not measure intelligence or ability, diagnose anything, or stand in for any professional assessment.
